Questions on Conversation Analysis (CA)

Hello. I have some questions on conversation analysis (CA) for the community. I am curious about how teachers are using CA here in Japan.

(1) Are you using CA in your English teaching?

(2) If so, how useful do you find CA in your teaching context?

(3) Do your students do unscripted recordings, then transcribe their conversations?

(4) Do your students find CA useful for learning English?

(5) What are some useful texts (articles, books) on doing CA, especially in Japan?

Thank you for your thoughts. I hope we all have a nice day.
